如何用owc（office web component）画图表

前段时间公司要用owc做图表，就研究了一下，发现这方面的资料很少，就贴个代码出来大家研究研究。

public partial class frmChartShow : Form
{
public frmChartShow()
{
InitializeComponent();
}
private void frmChartShow_Load(object sender, EventArgs e)
{
string[] X1 = { "0", "5", "10", "15", "20", "25", "30" };
string[] Y1 = { "1", "2.5", "3", "10", "15", "16", "17" };
string[] X2 = { "0", "5", "10", "15", "20", "25", "30" };

string[] DKY1 = { "2.5","10","17"};
string[] DKX2 = { "10", "15", "30" };
string[] DKY2 = { "2","12","18"};
this.picBoxChart.Image = System.Drawing.Image.FromFile(CreateLineChart(X1,Y1,X2,Y2,DKX1,DKY1,DKX2,DKY2));
